CONSTRUCTION OF MOLASSES-GATE.

Specification of Letters Patent No. 1,750, dated August 28, 1840.

To all 11i/2,0m i muy concer@ Be it known that I, AMMI VVEsT, of Greene,in the county of Kennebec, State of Maine, have invented a new andImproved Molasses-Gate; and I do hereby declare the following a full andexact description thereof-reference being had to the annexed drawingsmaking a part of this specification, in which- Figures l, 2, 3, and 4are referred to.

Fig. 4 is a perspective view; Figs. 8, 2, and l, sectional.

Similar letters refer to similar parts.

In Figs. l, 2, 3, and 4 of annexed drawings, letter A, represents theinside tube through which the molasses flows.

Letter B, represents the outside tube (shell or cap).

Letter C, represents the screw, which holds on the cap, B.

Letter D, represents the proj ect-ion or bead on inside tube.

Letter E, represents the handle on the cap B.

Letter F, represents the thread of the screw, on outside surface of A.

Letter G, represents t-he orifices o-n the sides of A, and B.

Letter I, represents the projection on the cap B.

Letter O, represents a space between the ends of tubes A, and B.

Letter N represents the teat in which a hole is cast for the screw C.

On one end of the inside tube (a) I have of the screw form, so as toprevent any leak when made fast in the hogshead, this end is o-pened toreceive the molasses, while the other is tight and of a true taper inthe center of this taper underneath I have the orifice (G) to let outthe molasses when desirable in the center of the taper or cap end (tubeA,) I have a hole, with the thread of a screw in the inner surface-thishole passes down and nearly through the teat N, and is made at the timeof casting and designed to receive the screw C.

The shell or cap (B) I make of sufficient length to cover entire thetaper on the tube before described, I yalso have it tapering so as tocorrespond with the taper of inside tube and to make an exact` fit whenon. Opposite the handle of the cap I have an orifice larger than the onein the inner tubethe larger I design to cover or shut by the smallerorifice at pleasure by turning the outside tube or shell for the purposeof drawing molasses. Between the ends of these tubes, as represented inFig. 3, letter O, I have a suflicient space to admit o-f the cap movingfarther on in case of wear of those parts which come in contactthis isdone by turning the screw, C. Should the cap gro-w too loose inconsequence of use in the end of the cap I have a small screw hole whichcovers the hole in the end of inside tube when the cap is on. The screwC, as in Figs. l and 3', passes through the hole in the cap and forms acenter on which the cap turns and enters the inside tube and made fastby its thread, in the hole designed for that purpose and beforedescribed.

On the inside tube as represented by D, in all the figures, I have abead or projection which passes about half around the tube. On the cap Ialso have a projection as sho-wn by I in Figs. l, 8, and 4. Turning thecap o-n the tube these projections come in contact, and the inner tubeturned by pressing the cap when desirable to make fast in the hogshead,and yet moves back easy so far as is wished to cover and uncover theorifice in the inner tube for the purpose of letting molasses flow. Onthe top of the cap I, have the handleE,` which is strong enough tosustain a heavy pressure-as the projections D, and I come in contactwhile placing the gate intoany vessel for use.

The screw C, is designed to hold on the cap in its proper place and toregulate the same in case of wear. On one end of inner tube I have thescrew thread F, for the purpose of making fast in the hogshead. Theholes o-r orifices shown by let-ters G, one in each tube cover and shutby each other as the cap is moved, so far as t-he projections willadmit. When one hole covers the other the molasses flows freely from thehogshead. Vhen shut by the stream is cut ofi'l and no leakage follows.

For the purpose of manufacturing, I have molds to cast the two tubes Aand B and design to have them come out so perfect as to need little orno finishin reality the labor being less in both tubes than in thescrewgiving a great advantage in manufacturing over all other gates. Themetal should be hard enough to prevent cohesive attraction.

Operation: When the faucet is properly put into the hogshead for use theorifices in the inner tube and cap the one is made to ing them by a setScrew in the manner set forth in my specications, so that when the capis screwed down uponthe inner tubeit shall owing to the conical form Ihave given the cap and tube be made to embrace the latter more closelyand thus prevent leakage as the parts Wear away.
